To all @horn c'meyconcem:

Be it known that I, Louis KEssLER, "a

citizen of the United States, residing at i Chicago, in the county of-Cooky and `State of- Illinois, have invented certain newand useful Improvements 'in Filler Tubes, of which the following isy a description.` i

My invention belongs to that general class of devices known as filler tubes, andk par-- t-icularly relates toan improved safety tube and closure` for the same.

The `invention has among-its objects the production of a device of the kind describedy that is'safe, simple, eficient, durable, "com -v pact and satisfactory for use kkwherever found applicable The invention has particularly `among itsr objects the production of a closure that may beused in connection with any suitablejform of filler tube .of filler opening'of a receptacle, for closing *the opening where the tank is filled, whereby excessive" pressure in the tankmay be relieved and where air maybe admitted tovr lill the space formerly occupiedy by the liquid as said liquid 4is being drawn from the tank. By this last-mentioned, incans, namely, the admittance ofzair into the tank while the contents therein are being drawn off, /the'creating of a vacuum in the tank and the consequenty impairing of? discharge is prevented, as well as collapsing of the tanlnand at the same "timethe escape of gas from the tankdue to evaporation is prevented. Danger of the tank con-` tents exploding is entirely done away with.v

n Many other objects and'adva'ntages of the construction herein vshown rand ldescribed will be obvious to those skilled in the art from the disclosureshereingiven To this 1 end my invention consists in the novel construction, arrangement and combinati'on of parts herein `shown, j and described, and more particularly pointedgoutk in the claims. f v f In the drawings, wherein like reference characters indicate f like or corresponding parts,v l Fig. 1 yis a top plan view of my device; l

device and approximately rig. i is a my device;

tion, there is shown a tank or other receptacle l adapted to contain liquids, and hav- 'ing a filling opening 2., My device is 'intended'to cooperate with vsaid tank at its llingopening to permit the filling thereof,

to prevent flamefenteringfthe tank, to re-. lieve excess pressure within the tank and to permit the admit-tance of air to thetank as the contents thereof are drawn oft'.4 A pair if ofy coaxial spaced tubes 3 and 4 are shown as extending intothe tank, said tubes'being turesjtherethrugh, and inI the present in# stance I providethe .outer tube with a fine wire gauze/at the interior, a gau'zeof ing preferred.

`front .View of my y 5w;ffl-:momen l In the drawings, wherein I have illustrat-v ed `the preferred embodiment lof my inven-` I110 `meshes to the linch bei The closed or lower end 7'of the inner v i ,tube may besupported and rest on thev lclosed end 8.o f the outer tube, if desired. VVhenthe tubes are provided with a" solid imperforate bottom wall, there is no danger ofunauthorized persons inserting a stick,

or the like, into the tank through the botytomv'walls of the tubes.`

A 'closure member comprising a plate 9 having a pairof annular, radially-spaced lflanges 10` and llprojectin'g from one face thereof, is arranged to cooperate with the filling opening of the tank and to ycarry the tubes 3 and 4, the flange 10` being preferably screw ythreaded sofas to'detachably vconnectwith the threaded flange of the opening 'of the tank, andthe flange 11k is also preferably screw ythreaded tol detach- `ably receive the threaded end ofthe outer tube 3. .The plate 9` is extended radially inwardly, past the flange 11,/ to form an annular se t 12 engageable With the outer open upper end ot the tube e, spacing it from the tube rlhe seat 12 may be brazed or soldered to the top oit the tube et, or may be otherwise joined thereto. The plate 9 has one or more ports or openings 13 therethrough, between the inner and outer tubes 4land S.

i cap 14, which is shovfn in the 'form of a dislr member, is adapted to be positioned on the plate 9 to control the openings oi both ol' said tubes, said cap covering the apertures 13 and havingv a checlr valve 15 therein. rlhe checlr valve comprises a chamber 15 having a duct 21 therethrough. il movable valre member 16 is engageable With said valve 17 formed in the dislr, said member 1G being` supportably carried by a member 1S pressed upwardly against the valve seat by a coil spring 19, said coil spring beadjustably and removably held in place by a `part 20. lt will be noted that the parts 1 8 and 2O also have bores therethrough communicating with the interior ot the tribes, and with said bore "Q1 communicating with o the atmosphere, vvhereby air may pass 'from the atmosphere through the check valve and into the tuliies and the tank.

A flange 22 is provided on the plate 9, projecting in a. direction opposite to that ol ythe 'tlanges 10 and 11, the flange beingless than a complete annulus and preferably semi-annular, as shovvn in Fig. 1. A pair of `arms are carried by said plate 9 rearwardly of said flange 29, and projecting' beo yond `the periphery of the plate 9.- l. rod

orpin 24 is pivotally secured between said arms said rod carrying a lever 25 apertured at its tree end as at 26. The valved disk ,les is pivoted to the lever 25 at 9,7, and a spring' 28 is arranged to cooperate with the lever to exert a pressure upon it to normally keep it in the position shown in "full lines in Fig. el, er, in other words, the spring 28 normally keeps the disk le tightly closed on its seat to close the open ends of the tubes 3. l

ln case of any pressure in the tank, caused for any reason Whatever, when the same reaches the point Where it overcomes the spring 2S. the vclosure disk 14 may litt slightly against said springl pressure so that the pressure Within the tank may be relieved through the ports 13, after which the disk drops `back into position, closing the receptacle. As the liquid is drawn oit Yfrom the tank. air may enter through the cheek valve 15 thereby in'eif'enting` a partial vacuum Within the tank, that T,vill interfere with the operation. lt is impossible for any flame to ,eet through the ,efauze covering the tubes and igniting the contents oi.: the tank. The device is, theretore, non-eplosive- The device therefore is ,an efficient safety device,

preventing the contents of the tank from becoming ignited and exploding.

Owing to the close mesh ot the gauze 5, any Water in the gasoline or fluid Will not through the tubes `and enter the tank. ,es the gasoline or tiuid is poured into the tank through the tubes, the Water, it it accumulates, Will loiv upwardly between the tubes and out `through the openings 13, the incoming' gasoline or fluid causing` this action.

ln order to lock the closure member 111 against tampering` by unauthorized persons, there is shoivn a .locking arm 29 bivotally secured to a projecting' lug 30 `at the side et the plate 9 dian'ietrically opposite to its pivotal connection With the lever 25. rlhe locking` arm 29 is preferably yolred and is bent to the form oit a bell-crank lever, Whereby its leg 31 will limit the pivotal movement P ie locking), arm, by abutting;` against the "e of the plate 9, as shown in the drawings, in which position the top edge of the lover `will a slight distance 'from the vtree end ot the yoke, so as to permit a little litt or play therebetween. The tree end of the .locki arm is provided with an aperture 32 which is adapted to cooperate with the aperture Q6 at the free end ot the lever, to reve padlock or-the like 233.150 lock said parts in prwition. will be noted tfiateven when the parts are locked in position, as shown in i" there is permitted a slight lifting l l i..ovement ot the lever 9.5 .and the dislr 1de carried thereby relative to the open ends of the tube and so that any excess et pres- H .-n the tanlrmay be relieved ivith ook in position, by the slight unseatinn' oi said disk.

Having thus described my invention, it

is `olu'ioue that various inmaterial modifica`- tiene he made in the same without. departing from the spirit o't my invention; hence l do not Wish to be understood as limiting myselr to the exact ntorni, construer tion. arrangement and combination of parts herein shown and described, or uses mentioned.
